Optimum observation of processes through transparent tanks
Bulk solids can be transformed from a fixed bed into a fluidised bed when liquids or gases pass through them. The areas of application of fluidised beds include the drying of solids and a wide variety of chemical processes.
Features two transparent test tanks for fluidised bed formation in water and air. A diaphragm pump delivers water from a storage tank into the bottom of the left side test tank. The water flows upwards through a porous sinteredmetal plate.
On the sinteredmetal plate is a bulk solid. If the velocity of the water is less than the socalled fluidisation velocity, the flow merely passes through the fixed bed. At higher velocities the bed is loosened to such an extent that individual solid particles are suspended by the fluid. If the velocity is increased further,particles are carried out of the fluidized bed. A filter at the top of the test tank holds these particles back. The water flows back into the storage tank.
The rightside test tank is similar in construction to the leftside one. An air flow generated by a compressor flows through it.
